Specification of Letters Patent.

Application filed March 12, 1906. Serial No. 305.618.

1'0 (all whom it may concern: i Be it known that we, CHARLES W. BUTLER and HIRAM C. BuT Lnacitizens of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have in- I you ted certain new and useful Improvements in Door-OperatingDevices; and We do del clare the-following to he a full, clear, and exact descriptiohof the invention, such as will i I art to which it apf pertains to make and use the same. I Our invention'relates to improvements in l door-operating devices, and more particularly to one ada ted for use on locomotives closing the fire-doors by pneumatic or other ower.

' The object of the invention is to provide a device of this character which will be simple,

constructionand very efficient in operation.

With the above and other objects in view our invention consists of certain novel features of construction, combination, and arrangement of devices, as hereinafter described and claimed.

in the accompanying drawings, Figure l is a detail vertical transverse sectional view through the flooring of a l mnnotivcwab, showing our improved operating dcvice applied to the fiirnace-door. Fig. 2 is a detail vertical sectional view taken on the plane indicated by the line 2 Zin Fig. 1. Fig. 3 is a Fig l is a secti'onal view tln'ough the valve and its casing. Fig. 5 is a detail sectional view of the rotary valve,-t'alwn' on thc plane indicated by the F line 5 5 in Fig. 4; and Fig. 6 is a detail view of l the rotary valve. 1

Referring to the drawings by numeral, .i denotes a portion of the deck or flooring of a loconnitivemab, and 2 denotes the head or the front of'thecaln r ()ur improved door-operating device may be used upon either swinging orsliding doors; but, as here shown, it is ada )t-d for opening and closing the two sliding doors 3 4..which close the-usual iire door opening in the moon l head 2. These doors-3 4 slide toward and from each other in upper and lower hon'ion; tally-disposed guides 5, arranged upon the I I l i l i i boiler-head, as shown. The door 4 is actuated by one arm 6 of a. Y-shaped' lever 7,

"mounted, as shown at 16.

bolted rovidc d at other arm 11' of the lever 7 is connected b a link 12 to a lever 13, which actuates the ot er door 3. The lever 13 has a slot-and-pin connection 1-1 15 with the door ,3, similar to the connection just described between the door 4 and the lever 7, and said lever 13 is pivotally The third arm 17 of the lever 7 arm of a hell-crank 19, which is pivoted at its angle, as at 20} u on the upper. portion of the boiler-head 2 am has its other arm connected by a link '21 to a sliding rod 22 of a piston 23, which slides in a cylinder 24. The latter is mounted upon the upper portion of the boiler-head 2 in any suitable manner. The piston 23 is rcciprocated in the cylinder 24 to open and close the doors 3 4 by admitting compressed air or other fluid under pressure into the ends of the cylinder upon opposite sides of its piston through pipes or similar connections 25.26. These pipes 25 26 lead to and are connected with nipples 27 28, providcd in a removable head or plate 29 on the cylimlcr-casing 30 ot a rotary controlling- 'alvc 3 L This valve-raising is disposed bencath the lloor or deck 1 of the cab and is formed with an attachirig-bracket 32, which is bolted or otherwise secured to said door, as shown in Fig; l ol the drawings.

The casing 3U is cylindrical in form, as is also the valve 31, and its open lzicc is closed by the circular plate or head 2!), which is or otherwise secured upon an annular flange lormcd on said casing. The rotary valve 31 is provided with ports or cavities 33 34, which react with the nipples or casings 237 28 and also with a similar connection 35, the rear of the casing, as shown.

The nipple or connection 00 is adapted to have a fluid-supply pipc connected to it, an

air pipc leading from the main reservoir on the engine or locomotive being preferably provilled,so that the piston-23 in the cylindcriM is actuated by compressed air. In the valve 31 is also provided a port or cavity 36,

which coacts with the connections .27 28 and also with an exhaust-opening 37, formed in is connected by a link 18 to one -33, 34, and 3c in the valve and the nipples or 5 connections 27, 28,35, and-'37 in the valvecaslng is such that when the valve 31 is shitted to one position the compressed air enter- ..4 -ing'through the inlet connection 3-5 can pass through one of the valve-ports, one of the 0 appleson the cover-plate, and one of the connecting-pipes between the valvecasing and the cylinder 24, so that its piston 23 7111 be actuated in one direction to move the doors 3y to either an opened or closed position.

When the valve is in this position, the air upon the opposite side of the cylinder-piston 23 is permitted to exhaust through the other pipe connecting the valve-casing and cylinder and out of the exhaust-opening 87 in the valve-casing, as will he readily understood. When the valve 31 is shifted to its other position, the compressed air will he admitted into the opposite end of the cylinder, and the doors will be moved in the opposite direction. The valve may be shifted to either of these twopositions by depressing either one of two push-rods 38 39, arranged vertically in. guide-- openings iii the floor or deck 1 of the cab.

Foot buttons or knobs are provided at the upper ends of these rods, and their lower ends are pivotally connected to a lever 40, which is secured at its center or at a point midway the pivotal connections of said rods, upon the shp-Jft or pivot 41 of the valve 31. This shaft 41 projects through the said valve and the casing 30, as shown. The lever is held in its normal horizontal position by means of coil-springs 42, which surround guide-rods 43 between a plate 44, through which. said. rods 4 43 slide, and the under face of the lever 40, to which the upper ends of the rod 43 are piv otally connected. The swinging movement of the lever 40 is limited by two stops d5 46, provided. upon the votive-casing, as shown, 45 so that when either of the rods 38 39 is deresscd the valve may be shifted to either of its two positions previously mentioned.

The construction, operation, and advantages of the invention will be readily unde 5 stood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that when one of the push-rods 38 39 is dopressed compressed air or oth or fluid under pressure will pass through 5 the rotary valve, its casing, oneoi the pipes 25 26-, and into one end of the cylinder :24 to actuate the piston 23 in one direction, and gtdlerehyshift the doors 3 ite either their opened or closed position by reason of the le ver connections between the piston-rod 22 6o and said doors. When the other of said pushthe invention as defined by the appended 7o claims.

Having thus described our invention, what we claim as new, and desire to secure by Lettors Patent, is- I 1. The combination of doors, means to op crate the same, a cylinder, a iston therein having a rod connected to sai door-operating means, a valve-casing, pipes leading from said casing to the ends of the cylinder, arotar-y valve in said casin to control ithe admission and exhaust of uid under'jtressure through said pi es, a shaft upon sai leasing, alever on said s iaft, stopsto limit the swinging movement of said lever, springs tobalance said lever between said stops,'and ush- 5 rods to actuate said lever in opposite. ircc. tions.

2. The combination 0t a valve-casing,

ipes leading from said casing, arotary velve 111 said casing for-controlling the admission 9 and exhaust of fluid under pressure through I said pipes, a shaft uponsaid valve and projecting through said casing, a lever upon said shaft, stops to limit the swinging movement I of said lever, springs for halancingsaid lever between said stops, and push-rods for actuating said lever iii-opposite directions, substantially as described.

3. The combination of a valve-casing having upon one side a supoly connection 35, I00

and upon its opposite sides connections 27, 28, and an exhaust-opening 37, a rotary valve in sa1d casing having ports 33, 34 and 36, a

shaft 4'1 projectin from said valve and through said casing, a lever for actuating said 95 shaft, and stops upon said casing to limit the movement of said lever, substantially as described. T

In testimony whereof we have hereunto our hands in presence of two subscribing I Iv witnesses.
